The Tánaiste and Foreign Affairs Minister has said he's more concerned about ending the genocide in Palestine rather than talking bout Glastonbury.
UK police are also investigating following performances by the punk-rap group Bob Vylan, and Belfast rap trio Kneecap at last weekend's festival.
US authorities say the London duo has been banned from entering America, over what authorities described as a "hateful tirade" during their appearance on the West Holts stage on Saturday.
The rappers have been accused of promoting hate speech by leading the audience in chants of "death to the IDF".
Their visas have been revoked ahead of a planned tour of the States later this year.
The US deputy Secretary of State, Christopher Landau, confirmed the news on X, saying, "foreigners who glorify violence and hatred are not welcome visitors to our country."
Bob Vylan's performance was livestreamed on the BBC iPlayer. However, it was later deleted and taken down from the online platform.

Both the BBC and the organisers of Glastonbury have condemned the chants heard during Bob Vylan's performance.
However, speaking ahead of a Cabinet meeting on Tuesday, Tánaiste Simon Harris says he'd rather talk about what’s happening in Palestine instead of what happened at a music festival.
"What I'd say is it's a matter for the police in the first instance.
"Artists obviously do art, and artists have freedom of expression - as does everybody in society.
"Of course, everybody has to operate in the law, and it's a matter for any police authority to determine that.
"But you know what I'm much more concerned about? Ending the genocide that's happening in Palestine."
